Adjusting The Turf Compensation Spring - Toro 03540 Operator's Manual

10. Coat the spline shaft of the motor with clean grease and
install the motor by rotating the motor clockwise so the
motor flanges clear the studs. Rotate the motor
counterclockwise until the flanges encircle the studs and
tighten the mounting nuts. Ensure that the washers are
against the nuts.

11. Detach chain from lift arm and secure it to cross tube on
each rear cutting unit with a capscrew, flat washer, and
locknut (Fig. 11).

Important
Make sure that all hydraulic hoses are
routed away from cutting unit so when cutting unit pivots
excessive rubbing does not occur.
12. Check adjustment of lock-up rollers (Fig. 12). When
properly adjusted, they will contact the lock-up levers
on rear lift arms and support the cutting units when
fully raised.

Adjusting the Turf
Compensation Spring
Note: This adjustment is needed for Cutting Unit Models
03527 and 03528 only.
The turf compensation spring (Fig. 13), connecting carrier
frame to cutting unit, controls the amount of fore-aft
rotation available.
The Turf Compensation Spring also transfers weight from
the front to rear roller. (This helps to reduce a wave pattern
in the turf, also known as bobbing.)
Important
Make spring adjustments with cutting unit
mounted to traction unit and lowered to shop floor.
1. Tighten locknut on rear of spring rod until the gap (C)
between rear of spring bracket and front of washer is
1.25 in. (32 mm) (Fig. 13).
2. Tighten hex nuts on front end of spring rod until the
compressed length (A) of spring is 6.25 in. (328 mm)
(Fig. 13).
Note: As compressed spring length (A) decreases, weight
transfer from front roller to rear roller increases and carrier
frame/cutting unit rotation angle (B) decreases.
Note: As gap (C) between spring bracket and washer
increases, carrier frame/cutting unit rotation angle (B)
increases.
